MADYMO used for computer aided design of a dynamic acting child restraint seat
Published September 09, 1980 by International Research Council on Biokinetics of Impact in Switzerland
A child restraint system based on a new concept was computer designed and optimized. This unique child restraint system is based on a moving impact shield. The shield is horizontal during normal use, so the child can have good forward visibility, but during a frontal collision the shield pivots upward to restrict the forward motion of the child's head and thorax. The first stage of this study was to design and optimize the actuating mechanism of the dynamic shield. In the second stage, the performance of the restraint system was optimized for the TNO-P3, 3-year-old child Dummy. The optimization of the design was carried out in both stages by varying the geometry, padding, and inertial properties, using the MADYMO Crash Victim Simulator. The final stage of the study was to perform sled tests to validate and refine the design of the system
